The composition of the drum core, what the drum is made of

Printers and photocopiers have the same drum core structure, but the coating formula is different.

Generally, the drum core is composed of a support body (aluminum tube) + a barrier layer (UCL) + a generating layer (CGL) + a transport layer (CTL), and a protective layer is added to increase the life.

The construction principle of the toner cartridge The laser printer is made according to the principle of laser scanning technology and electronic imaging, and its printing process can be briefly described as follows: the laser beam with information and processed is irradiated on the photoreceptor drum, so as to form a latent image with a positive charge, and the toner with the opposite charge is attracted to form a toner image on the photosensitive drum, and the printing paper that has been applied to the attraction voltage will transfer the "toner **" to the paper when passing through the photoreceptor drum, and then pass through the melting printing device, and the "toner **" will be heated and pressurized. The image is fixed and the entire printing process is completed.

Among them, the imaging and development process is mainly done by an accessory called a toner cartridge. The toner cartridge is to put some consumable and vulnerable parts, such as toner, photosensitive drum, and scraper in a box, which simplifies the maintenance of the printer. The two main elements in the toner cartridge:

Toner and drum. Toner is composed of iron sand, resin and carbon powder, and the surface elements of the drum are mainly composed of selenium and some rare elements, selenium is much more expensive than **, one gram of selenium can be plated with 200 photosensitive drums like HP92298A, so the toner cartridge is also called a toner cartridge.

There are two types of toner cartridges: integrated toner cartridges and discrete toner cartridges. The design of the integrated toner cartridge is mainly to install the toner and the photosensitive drum on the same device, when the toner is exhausted or the photosensitive drum is damaged, the whole toner cartridge has to be scrapped.
